Description

Detailed Description of the Invention This invention arranges a needle shack in the needle groove behind one knitting needle so that it can move forward and backward, and the butt of this needle jack is moved above the needle bed by an electrical or mechanical needle selection device. In an I-lock or multi-hook type flat knitting machine, which is configured to be selectively controllable to at least two or more different positions including a forward position and a backward position, the stitch transfer function is combined. This invention relates to a knitting cam device.

Various types of flat knitting machines equipped with stitch transfer devices have been developed to obtain stitch transfer patterns and/or to reduce stitches during the knitting process.

However, in the conventionally known cam device having a stitch transfer function, firstly, the relationship between the traveling direction of the carriage and the stitch transfer direction that can be transferred by one set of front and rear stitch transfer cam devices is different for each flat knitting machine. As shown in Fig. 1, in the most basic type, when the carriage moves to the right, a pair of front and rear transfer cam devices on one side transfers the stitches from the front side to the rear side. When moving, it is possible to transfer the stitches from the rear side to the front side using the front and rear sets of transfer cam devices on the opposite side, and as shown in Fig. 2, the front and rear sets of transfer cam devices are used to However, the running direction of the carriage that can be moved by a set of front and rear transfer cam devices is limited to either rightward or leftward movement.

One object of the present invention is to use one set of front and back shift cam devices to prevent the carriage from being moved in any direction, as shown in the figure, without specifying the direction in which the carriage is running. It is an object of the present invention to provide a transfer device that can transfer the stitches in any direction.

In addition, in FIGS. 1 to 4, T represents a transfer cam group that constitutes a transfer position guide track.

R is a receiving cam group which constitutes a receiving position guide track, and N is a normal knitting cam group which constitutes a knit position or tuck position guide track. In the figure, arrow C indicates the traveling direction of the carriage, and arrow t This shows the possible transfer direction in the traveling direction C of the carriage.

That is, the cam group T-R indicated by the thick line is a cam group that can be controlled to the operating position for stitch transfer when the carriage is moved in the direction C.The cam group T-R indicated by the thin line -R is a cam group that cannot be controlled to the operating position for stitch transfer when the carriage is moved in the C direction.

In addition, in the conventionally known knitting cam device with a stitch transfer function,
Second, the cam group TR for stitch transfer and the normal cam group N for forming stitches are normally at different phases in the direction of movement of the carriage, as seen in Figure 1.2. Because the width of the carriage was set at 1%, the width of the carriage was inevitably increased to 1%.In multi-cut flat knitting machines, intertwined with the above-mentioned requirement for transferable directionality, the width of the carriage became extremely long. There was a problem with it becoming.

However, in conventional devices, there is also a cam group T for transfer.
In some cases, the inclination of H and the normal cam group N for forming stitches are provided in the same phase in the direction of movement of the carriage;
In addition, as shown in FIG. 4, on one of the front or rear needle beds, the normal knitting cam group N
The cam groups T and R for stitch transfer are not both provided together, but the cam groups T and R for transfer are provided at different phases as shown in FIG. With something that
The direction in which the stitches can be transferred is limited by the pair of front and rear transfer cam devices.

Another object of the invention is to use the transfer cam groups T and R to make it possible to transfer the stitches in both the front and rear directions, even when the carriage is traveling in either the left or right direction, as described above. Together with the eggplant.

It also has a cam group N for forming one normal stitch on the carriage in the same phase as these stitch transfer cam groups TR,
The present invention aims to provide a new knitting cam device.

As mentioned above, the knitting cam device of the present invention is particularly advantageous in that the needle jack is electrically or mechanically operated between two or more forward and backward positions on the needle bed, that is, between an active position on the needle bed and an inactive position within the needle bed. The above objective problem is solved by taking advantage of the advantages of a flat knitting machine that can be controlled by a needle selection device, that is, by skillfully utilizing the existence of the needle selection mechanism in such a flat knitting machine. However, the gist of this is that in a 10-hole or multi-hole flat knitting machine having a needle selection mechanism as described above, the knitting needles and the needle jack are directly connected in the forward and backward direction of the knitting needles. At least one pair of locks arranged in front and rear on the carriage are arranged above and below in the same phase on the cam plate, respectively, and the cam group X acts on the butt of the needle jack. and a cam group Y that acts on the butt of the knitting needle, and the cam group
In the center position of - the butt of the needle jack in the forward position
On the other hand, a retractable register-ping position jack raising cam with a pushing-up surface that can act from either the left or right direction and push it up to the receiving position at the central position is placed on both sides of this receiving position jack raising cam. Then, a pair of retractable tuck position jack raising cams each having a lifting surface that acts on the butt of the needle jack in the forward position at the leading position of the receiving position jack raising cam to push up the needle jack to the tuck position. , a pair of push-up surfaces are provided at positions above the registering and pinging position jack raising cams between the pair of tank position jack raising cams, which act on the butt of the needle jack in the tuck position to push the needle jack up to the knitting position. The cam group Y is located at least in the center of the cam group in either the left or right direction with respect to the butt of the knitting needle pushed up to the tuck position or the knit position. The retractable type has a push-up surface that can act even from the ground to push it up to the transfer position, and a guide surface that acts on the butt of the knitting needle pushed up to the receiving position and forms the receiving position guide trajectory of the knitting needle. The present invention includes a transfer position raising cam and a transfer position guide cam having a guide surface forming a transfer position guide track between the transfer position raising cam and the transfer position raising cam.

Next, the present invention will be explained in more detail by referring to an example. In this example, a pair of carriages 2 ,2′
When applied to a normal type of flat knitting machine that moves back and forth, the front needle bed 1, the rear needle bed 1'El, the front carriage 2, and the rear carriage 2' each have main needles. A similar device is provided according to the invention so that the rear needle bed 1
' and the carriage 2' are omitted from the drawings, and the following explanation will mainly be about the front needle bed 1 and the front carriage 2.

As shown in FIG. 5, each needle groove 4 into which a knitting needle 3 is received so as to be freely advanced and retracted has a length that allows a needle jack 5 to be received so as to be freely advanced and retracted behind one knitting needle 3. A needle jack 5 with a butt 6 projected onto the needle bed is arranged there.

The needle groove 4 is deep enough to receive a select jack 8, which will be described next, in a position above the needle jack 5 behind the butt 6 of the needle jack so as to be able to move forward and backward and swing freely. Above each needle jack 5 in the needle groove 4, a convex portion 8a formed on the lower surface of the front end is located behind the butt 6 of the needle jack. When it collides with the rear surface, the select jack 8, which can push out against the needle jack 5, is loosely sandwiched near its front end between the straps 11 and 12 of the needle bed 1, and is moved forward and backward, and is pushed forward and backward. It is arranged so that it can swing freely.

It is happening.

Next, the knitting action and stitch transfer action by the knitting cam device according to the present invention will be explained in the seventh section with respect to the device of the above embodiment.
To explain with reference to Figures 7 to 14, Figures 7 to 13 are as follows:
In each case, the relationship between the cam device and the passing positions of the butts 22 and 6 of the knitting needles 3 and needle jack 6 when the carriage moves to the left is shown by the cross-sectional shape of the butts. Regarding the retractable cams 23, 24, 25°26, 28, and 33, in order to make it easier to understand, only those that are restrained in the protruding position when the carriage moves in the direction of the arrow are illustrated, and those that are controlled in the retracted position are shown. I intentionally omitted the illustrations.

In the flat knitting machine of this embodiment, the needle selection device 50 sorts the knee kale jacks 5 into two groups: (A) group (1 position) and (B) group (■ position). , the needle selection for these two positions I and .

In the course before the carriage turns back in the direction of the arrow shown in the figure, the needle selection device 50 selects one needle and moves it forward from the ■ position to the I position by the action of the cam 17, and then moves the needle as shown in the arrow. This is done by entering a turnaround course.

The case is shown in which the knitting needles 3 of the (4) group are made to tack by advancing to the tank position, and the knitting needles 3 of the <Bl group are made to miss.

FIG. 9 shows a case in which the cam group Y is equipped with a radiating cam 33. In this figure, 2 glues 7' (4) and 2 glues 7' (4) selected at 2 positions I and If in the same manner as above are shown. (
Among the needle jacks 5 and knitting needles 3 in B), the knitting needles 3 in the (A) croup are the needle jacks 5 in the (A) group.
The needles 3 in group (B) are knitted by projecting the cams 24 and 25, and tacked by projecting the needle raising cam 33.

In Figure 10, the knitting needles 3 of the prisoner group are knitted in the same way as in Figure 9 above, and (B) a difference in height is provided in the butt 22 of the knitting needles 3 of the group.

By projecting the needle raising cam 33 to the half position (indicated by the chain line) and making it act only on the high butt knitting needles 3 in the (B) group, (B)
This shows a case where the knitting needle 3 with a high batt among the knitting needles 3 in the group is made to tack, and the knitting needle 3 with a low batt is made to tack.

In the figure, the butt 22 of the high butt knitting needle 3 is shown as a filled-in cross section, and the butt 22 of the low butt knitting needle 3 is shown as an outlined cross section.

Next, Figures 11 to 13 show the stitch transfer action, and Figure 11 shows only the needle jack 5 on the front needle bed 1.
As mentioned above, select the two positions I and H, and on the front cam plate 21, set the jack raising cam 24 at the tuck position.
(4) By protruding the transfer position raising cam 28, the needle jack 5 of the group
and the cam 24, only the knitting needles 3 of the (A) group,
After pushing it up to the tuck position, it is further pushed up to the transfer position by the action of the cam 28, and on the rear needle bed 1', all the needle jacks 5' are selected to the forward position I', and The receiving position jack raising cam 23' is activated to push up all the knitting needles 3' to the receiving position, and the concave guide surface 28 of the transfer position jack raising cam 28'
By guiding it to the receiving position with C, the stitches of the knitting needles 3 of group (4) are directed to the corresponding knitting needle 3 on the rear needle bed 1' on the right side of the center of the cam X-Y. This shows the case where it is transferred.

What is the transfer effect in this case? First, where the knitting needles 3 of the front needle bed 1 are pushed up to the transfer position at the center of the cam group X-Y, the knitting needles 3' of the rear needle beds 1'f and 1'f are pushed up to the receiving position. , @ While the needle 3 is held at the transfer receiving position by the guide surface 28'C of the transfer position raising cam 28', the knitting needle 3 on the front needle bed 1 is pushed down from the most protruding transfer position. It will be done.

Figure 12 shows the front needle bed 1 as in the case of Figure 11 above.
This shows the case where the knitting needles 3 in group (4) above are transferred to the knitting needles 3' on the rear needle bed 1'.
In the same figure, the needle selection mechanism is also operated on the rear needle bed 1', and the needle jack 5 on the needle bed 1' is moved (Af
(B) After selecting needles into two groups, (4) only the low θ゛ loop knitting needles 3' corresponding to the knitting needles in group (4) are set to the receiving position jack raising cam 2 in the same manner as above.

Unlike the case shown in FIG. 11, it is not pushed up to the receiving position.

FIG. 13 shows that the pushing-up surface 23a of the receiving position jack raising cam 23 is large enough to act on the butt 6 of the needle jack 5 in both the forward position I and the backward position (3). Regarding the case of another embodiment in which the receiving position jack raising cam 23 is configured to have a large size 123 as shown in FIG. 13, when transferring stitches, the front needle The needle was selected to advance position I on floor 1 (A)
Rear needle bed 1 corresponding to group needle jack 5
Put the jack 5' of the upper (4) loop in the retracted position■
The needles are selected on the rear needle bed 1' corresponding to the needle jacks 5 of the (B) group, which are set to the backward position on the front needle bed 1. After selecting needle I, cam play receiving position jack raising cams 123, 123', tuck position jack raising cams 24.24' and transfer position raising cams 28.28') 21.21'75
), at the center position of cam group
The stitches of the knitting needle 3' of the (BY';Z'' loop are transferred from the back to the front to the knitting needle 3 of the (B) group) (see FIG. 14).

The receiving position jack raising cam 123 of the embodiment shown in FIG. 13 is divided into two parts as shown in FIG. The system is composed of a similar receiving position jack raising main cam 23 and a receiving position jack raising auxiliary cam 100.

Each cam 23, 100 may be configured to be able to control its appearance and retraction separately, and in the case of this embodiment,
When the receiving position jack raising cam 100 is controlled to the retracted position, it functions exactly the same as the cam device shown in FIG.

Further, the above embodiment describes an example in which the present invention can be implemented with respect to a flat knitting machine configured to be able to selectively control the butt of a needle jack to the forward position I or the backward position ■ by an electric needle selection device. However.

The needle selection device is not limited to an electrical needle selection device, and the knitting cam device of the present invention uses a mechanical needle selection device, such as a pattern board or a pattern drum, etc. Needless to say, this method can also be applied to devices in which the jack can be set in two or more forward and backward positions.

Although the present invention has been described above with reference to the embodiments, in the knitting cam device of the present invention, as can be easily understood from the above, a pair of upper and lower cam groups X- Y is provided with a raising action surface that can act on the butt of the needle jack from either the left or right direction when the carriage is traveling to push up the selected knitting needle to the tuck position or knit position, and this cam group X-Y , the stitch transfer function is also provided, but in the cam device of the present invention, the stitch transfer function is always carried out at a stage before the X-Y center of the cam group when the carriage is traveling.
Only the knitting needles selected from one needle bed side are pushed up to the transfer position, and while they are kept at the transfer position, they are moved backwards from the center position of the cam group The knitting needles are pushed up from the needle bed side to the receiving position. It has the great advantage of being able to do this at will, even in the direction of.

Therefore, by using the lever and the 10-knit cam device of the present invention, it is possible to form normal stitches on the course when the carriage is traveling in any direction, as well as in both the front and rear directions. It is possible to freely transfer any stitch in any direction, and to perform pattern knitting using a combination of normal knitting, tucking, and mistakes, as well as reducing stitches, stitch transfer pattern stitching, etc., can be arbitrarily selected. .

Therefore, when the knitting cam device of the present invention is configured as a double lock or a triple lock, the knitting cam device of the present invention performs normal knitting for each lock in one course even when the carriage is traveling in either the left or right direction. You can arbitrarily select the action or transfer action, and in the transfer action, you can arbitrarily select the direction of the transfer, either forward or backward, and you can freely combine these actions, making it very easy to use. This allows for efficient transfer and organization.

Moreover, in that case, without increasing the carriage width,
It is possible to provide such a function to the carriage.

Furthermore, as explained in the above embodiment (Fig. 12), by skillfully combining one needle selection mechanism, only the selected knitting needles can be guided to the receiving position. The following troubles occur when knitting needles on the receiving side needle bed that do not receive stitches pass through the receiving position, namely:
If the stitches are pushed up unnecessarily by the knitting needles, the stitches will become untidy and there is a risk of dropped stitches. This eliminates troubles such as the possibility that the knitting yarn at the rest position may be fed even when the knitting yarn is not present.
In the knitting cam device of the present invention, the knitting needles and the needle jack are not connected, and the cam that pushes up one knitting needle to the receiving position is formed on the cam group X side that acts on the butt of the needle jack. In contrast, in the cam group Y, only the guide surface 28c on the lower surface of the transfer position raising cam 28 acts on the front surface of the butt of the knitting needle passing through the receiving position. There is an empty space between the lower surface and the neutral position trajectory of the knitting needles during stitch transfer, so if a problem occurs with the butt of the knitting needle pushed up to the receiving position, it will be removed from the empty space. Since the knitting needle can escape from the knitting needle, troubles such as subsequent knitting needles being damaged do not occur.

Therefore, according to the knitting cam device of the present invention, since it has a stitch transfer mechanism, it is also economical in that the consumption of expensive knitting needles due to breakage is reduced accordingly.
